to make a. plaster boardsimilar tothat shown and describ in, my United States fby machine or otherwise,

View taken substanl plaster board have been made heretofore,

both in molds and by a continuous method but the apparatus used in the manufacture has been more or less crude and ,depended to a large extent upon the skill of the operators, and the product has not been uniform. rll`he present machine is intended to be operated by a minim'uml number Aof operators, to have a greater output and yet to produce animproved uniform product, the machine being so constructed that boards of various Widths and thicknesses as Well as of single or multiple ply, the machine being readily adjusta- `ble to produce lthe various products which..

may be required.

I shall .first briefly describe the product itself, as with a clear understanding as to the product to be produced, the machine Will` probably be better understood and the pur-' poses of -the variousr coperating fmechanisms be clear. The plaster board conslsts of a suitable body of plaster, plaster Paris or other suitable plastic material,- Which is covered with a fibrous material, for example'paper, upon the two edges and opposite sides. of the board, sheets of fibrous material or the equivalent being embedded inthe plastic body if desired. Referring to Fig. 23, 1 representsthe body which is inclosed on the two `faces by the covering sheets 2 and 5, one sheet, as shown sheet 2, being folded up as at 3 to inclose the edge on both sides with i the extreme edge 4 folded over to overlie the body. In the board shown, part 4 is folded over Athe body and c'over sheet 5 then superimposed, the same being q f a Width to extend over the folded' edge part 4.v 'lVhen'v so constructed, however, the same is preferably of a Width so that it is .spaced back a'suitable distance, as'for example asat S, at each side; lVhere the edge 4'is superim-l posed over sheet 5, then the sheet 5 is ofa Width toleXtend'to the part 3. The parti'cular sample of board illustrated-contains the fibrous sheets 6, it being understood that these may be omitted if desired. Themachine illustrated is adapted to produce a board with or Without the sheet 6, Whichever may be preferred. The end or edge 4 and sheet 5 are sealed together" in .any suitable ma.nner,preferably by ,letting the plastic material'flow between vvthe vsaine as indicated at 7, regardless of which part is superimposed vabove the other. For the fibrous material I ordinarily prefer to use 'I score the same substantially at the points 8 and 9 so that the same may be bent easily.

-The board is ordinarily formed at both edges as described and is a continuous board which is cut off in the desired lengths at the end of the machine. rl `he plastic material, when the sheets 2 or5 are applied, is in a 'plastic condition or more or less semi-fluid,

the same setting or hardening before the cutting off mechanism is reached, which mechanism is usually placed near the end of the',

machine. From here it is taken from the machine and generally passed through a kiln. I have not considered it necessary,I

' `hbwever, to describe in detail the handling ofthe same after it is cut 0E, as this forms no part of the present invention.. Where the paper is specified as a covering in the ner. The conveyer 12 is supported between the pulleys 13 and 14 by rolls 15 lor the equivalent. The conveyer also passes between one or more pairs of rolls, three pairs '.x/ being shown, 16A-17, 18-19 and 20--21, the

, purpose of which `will be explained in detail hereafter. 'The paper. or other fibrous material ordinarily comes in rolls and is fed vtherefrom into the machine. Roll y22 represents the roll from which the cover sheet 2 is drawn, roll 25 that from which sheet 5 is` drawn and rolls 26 -26 the rolls from which l sheets 6-.6 are drawn.

These rolls'of paper are usually of conto handle. It is necessary to change or renew the rolls from time toV timel and desirable to make the change as quickly as posf sible asJthe plastic material, depending upon The a enrolls when in o erative ositionl p p P P may be adjusted on the shaftf-f Obviously,

' the kind used, sets more or lessfrapidly.

To facilitate `the handling of'the paper to be fed tothe machine, I carry the rolls from an upper-supporting frame consisting of the ,columns 29 supporting the beams 28.

-As most clearly shownin` Figs. 2 and 8v, the columns or standards 29 carry standards be conveniently'carried 'and unrolled. The rolls shown are arranged on shafts 31 which are provided with core members 32preferably -ilanged as at 33. The shafts 31 are of a length to 'project over and be carried by 70 the bearings 34, at one side'of which is a stop 35 and at "the other side an inclined support 36. When the hoisting mechanism shown is employed the same is provided with movable brackets 37 arranged to carry ,the` 75 shaft and roll of paperand lower the same to a point where the shaft 31 may be rolled down the incline 36 onto its bearing 34.

When seated shaft 31 clears the brackets 37, f which may then be raised. Brackets 37 are v480 shown mounted on travelers 38, each having engaging parts 40 constructed to engage with the part 30, as most clearly shownin Figs. 8 and, 9. A screw member 39 is arranged to actuate the .traveler 38,-which in Athe construction shown is`provided with a 4 v non-rotatable nut l41 threaded to engage the` siderable weight and consequently diiicult 550. Obviously,

4may be secured in place on the shaft in any screw 39. .A mechanism similar to that dev scribed is arranged at each side of the. end. of the roll of paper (see Fig. 3), and mech- 90 anism provid1ed with, simultaneously op,-

yerating the jack-screws 39 constituting the hoist, so that the paper may be evenly lifted into place. This mechanism is most clearly shown in Figs. 2, 3 and 8. ACarried by each upright part 30 is a bracket 42 which car-q ries shaft 43, upon which may be arranged a sprocket wheel 44 or the equivalent. Sprocket chain 45 is arranged -to drive sprocket wheel 46, one foreach upright 30, which drives shaft 471, and through the bevel gearing 48 drives the screw shafts 39 4in unl son. Shaft 43 may be operated-by providing a pulley 49 and'chain or the equivalent as shaft 43 is driven through the mechanism described brackets '37 are lifted or lowered. Arranged atone side of the roll of paper is a shaft 54 provided with flange members 51 (Fig. 2), one of whlch suitable manner, and the other of'which is i pfreferably yieldingly secured and maintained 'in operative position to engage thev '-1 30, forming part of paper handling lifts orl 'hoists While any suitable means may be provided for handling andl supporting the rolls of paper, my preferred mechanism is shown in Figs. 1, 3 and 8, it being understood that mechanism is providedv for each roll, and 'these being similar, a description of one will suiiice for all, portions of one bein shown'on one figure and similar portions o others being shown vin other figures, depending upon where the section or view is taken.

in the construction shown4 are 4carried by thefupper end of the' columns 29. Usually a core is inserted in the roll so that ltmay `edge of he paper'by spring 52 or the equivequivalent at each side,

alent. Referring to'Figs. 2 and 8, shaft 5 4 is provided with' a gear wheel 55, or the arranged lolrraclis 56 carried by the frame bars 28. A welght 57 is connected to a cable 58, and thiscatends over pulley59 and pulley 60 and 1s120 secured to shaft 54, the same tendlng to move shaft 54 toward shaft 31 as the paper is unwound and maintain the flange members 51 in close engagement with the roll of paper, retarding the unreeling of the paper 125 and guiding orcauslng 1t to run true. Theflanges are preferablyarranged so that they cause the shaft 54 to move parallel at all
